1 diff.autorefreshindex::
2 When using 'git diff' to compare with work tree
3 files, do not consider stat-only change as changed.
4 Instead, silently run `git update-index --refresh` to
5 update the cached stat information for paths whose
6 contents in the work tree match the contents in the
7 index. This option defaults to true. Note that this
8 affects only 'git diff' Porcelain, and not lower level
9 'diff' commands such as 'git diff-files'.
11 diff.dirstat::
12 A comma separated list of `--dirstat` parameters specifying the
13 default behavior of the `--dirstat` option to linkgit:git-diff[1]`
14 and friends. The defaults can be overridden on the command line
15 (using `--dirstat=<param1,param2,...>`). The fallback defaults
16 (when not changed by `diff.dirstat`) are `changes,noncumulative,3`.
17 The following parameters are available:
18 +
19 --
20 `changes`;;
21 Compute the dirstat numbers by counting the lines that have been
22 removed from the source, or added to the destination. This ignores
23 the amount of pure code movements within a file. In other words,
24 rearranging lines in a file is not counted as much as other changes.
25 This is the default behavior when no parameter is given.
26 `lines`;;
27 Compute the dirstat numbers by doing the regular line-based diff
28 analysis, and summing the removed/added line counts. (For binary
29 files, count 64-byte chunks instead, since binary files have no
30 natural concept of lines). This is a more expensive `--dirstat`
31 behavior than the `changes` behavior, but it does count rearranged
32 lines within a file as much as other changes. The resulting output
33 is consistent with what you get from the other `--*stat` options.
34 `files`;;
35 Compute the dirstat numbers by counting the number of files changed.
36 Each changed file counts equally in the dirstat analysis. This is
37 the computationally cheapest `--dirstat` behavior, since it does
38 not have to look at the file contents at all.
39 `cumulative`;;
40 Count changes in a child directory for the parent directory as well.
41 Note that when using `cumulative`, the sum of the percentages
42 reported may exceed 100%. The default (non-cumulative) behavior can
43 be specified with the `noncumulative` parameter.
44 <limit>;;
45 An integer parameter specifies a cut-off percent (3% by default).
46 Directories contributing less than this percentage of the changes
47 are not shown in the output.
48 --
49 +
50 Example: The following will count changed files, while ignoring
51 directories with less than 10% of the total amount of changed files,
52 and accumulating child directory counts in the parent directories:
53 `files,10,cumulative`.
55 diff.external::
56 If this config variable is set, diff generation is not
57 performed using the internal diff machinery, but using the
58 given command. Can be overridden with the `GIT_EXTERNAL_DIFF'
59 environment variable. The command is called with parameters
60 as described under "git Diffs" in linkgit:git[1]. Note: if
61 you want to use an external diff program only on a subset of
62 your files, you might want to use linkgit:gitattributes[5] instead.
64 diff.ignoreSubmodules::
65 Sets the default value of --ignore-submodules. Note that this
66 affects only 'git diff' Porcelain, and not lower level 'diff'
67 commands such as 'git diff-files'. 'git checkout' also honors
68 this setting when reporting uncommitted changes.
70 diff.mnemonicprefix::
71 If set, 'git diff' uses a prefix pair that is different from the
72 standard "a/" and "b/" depending on what is being compared. When
73 this configuration is in effect, reverse diff output also swaps
74 the order of the prefixes:
75 `git diff`;;
76 compares the (i)ndex and the (w)ork tree;
77 `git diff HEAD`;;
78 compares a (c)ommit and the (w)ork tree;
79 `git diff --cached`;;
80 compares a (c)ommit and the (i)ndex;
81 `git diff HEAD:file1 file2`;;
82 compares an (o)bject and a (w)ork tree entity;
83 `git diff --no-index a b`;;
84 compares two non-git things (1) and (2).
86 diff.noprefix::
87 If set, 'git diff' does not show any source or destination prefix.
89 diff.renameLimit::
90 The number of files to consider when performing the copy/rename
91 detection; equivalent to the 'git diff' option '-l'.
93 diff.renames::
94 Tells git to detect renames. If set to any boolean value, it
95 will enable basic rename detection. If set to "copies" or
96 "copy", it will detect copies, as well.
98 diff.suppressBlankEmpty::
99 A boolean to inhibit the standard behavior of printing a space
100 before each empty output line. Defaults to false.
102 diff.<driver>.command::
103 The custom diff driver command. See linkgit:gitattributes[5]
104 for details.
106 diff.<driver>.xfuncname::
107 The regular expression that the diff driver should use to
108 recognize the hunk header. A built-in pattern may also be used.
109 See linkgit:gitattributes[5] for details.
111 diff.<driver>.binary::
112 Set this option to true to make the diff driver treat files as
113 binary. See linkgit:gitattributes[5] for details.
115 diff.<driver>.textconv::
116 The command that the diff driver should call to generate the
117 text-converted version of a file. The result of the
118 conversion is used to generate a human-readable diff. See
119 linkgit:gitattributes[5] for details.
121 diff.<driver>.wordregex::
122 The regular expression that the diff driver should use to
123 split words in a line. See linkgit:gitattributes[5] for
124 details.
126 diff.<driver>.cachetextconv::
127 Set this option to true to make the diff driver cache the text
128 conversion outputs. See linkgit:gitattributes[5] for details.
130 diff.tool::
131 The diff tool to be used by linkgit:git-difftool[1]. This
132 option overrides `merge.tool`, and has the same valid built-in
133 values as `merge.tool` minus "tortoisemerge" and plus
134 "kompare". Any other value is treated as a custom diff tool,
135 and there must be a corresponding `difftool.<tool>.cmd`
136 option.
